Have you ever caught your cat sleeping for what feels like the entire day? You’re not imagining it. Cats are expert nappers — and there's science behind every stretch, snore, and blink.

In this guide, we explore why cats sleep so much, what their sleep cycles look like, and how to choose a cat bed that enhances their rest and overall health.


How Long Do Cats Sleep?

On average, cats sleep 12 to 16 hours a day. Senior cats and kittens can snooze up to 20 hours! Unlike humans, cats are polyphasic sleepers — they sleep in multiple short bursts throughout the day and night.

Each nap plays a crucial role in:

  • Tissue repair
  • Memory processing
  • Immune regulation
  • Stress recovery

Understanding Cat Sleep Cycles

Cats cycle between two sleep phases:

1. Light Sleep (Catnapping)

  • Lasts 15–30 minutes
  • The body is resting, the brain stays alert
  • Ears twitch, tail flicks — ready to wake at any sound

2. Deep REM Sleep

  • Shorter, but more critical
  • This is where real healing and dreaming happen
  • Usually occurs when your cat feels 100% safe

A high-quality, secure bed helps cats spend more time in REM sleep, improving mood, mobility, and immunity.


How to Create the Ideal Cat Sleeping Environment

Cats are particular — they don’t want to nap just anywhere. To support better, deeper sleep:

  • Provide enclosed or structured beds for safety (like a felt cave)
  • Place beds in warm, quiet zones with natural light
  • Keep their bed clean and free from odors or pet hair buildup
  • Rotate locations occasionally to keep things interesting

Vet tip: Senior cats benefit from low-entry beds and warmth-retaining felt to ease joint pain and stiffness.


Best Cat Beds to Improve Sleep Quality

  • 3-In-1 Cave – transforms to match every sleeping style
  • Felt caves – enclosed and calming, perfect for deep REM naps
  • Flat felt pad – best for open sleepers and sunny window lounges
  • Felt houses – add personality to any nap zone

All PURRZ beds are vet-designed and durable, and the caves are made from felt — one of the best materials for restful sleep.


From Our Vet, Dr Duncan Houston

“Cats sleep more than any other domestic animal. The right bed isn’t a luxury — it’s critical to long-term health. Comfort, structure, and warmth help promote longer REM cycles, which in turn support everything from mood to muscle repair.”
— Dr Duncan Houston

Cat Sleep = Cat Health

When you invest in a better bed, you’re doing more than spoiling your cat. You’re supporting:

  • Brain development (especially in kittens)
  • Joint & muscle recovery (for seniors)
  • Stress reduction (for anxious cats)
  • Bonding — because well-rested cats are happy cats
